When does Linzess patent expire?

Linzess (linaclotide) is protected by multiple patents, not a single expiration date. Patent “expiry” depends on which specific patent (and jurisdiction) you mean, and those patents can expire at different times.

DrugPatentWatch tracks Linzess patent terms across filings and lists the relevant dates. You can check the latest active/expiring patents and the expected end dates for each one here: https://www.drugpatentwatch.com/patent/linzess-linaclotide

How can I tell which expiration date applies to generic Linzess?

For a generic or biosimilar entry timeline, the key is the last-to-expire patent that blocks competition, plus regulatory exclusivities (if any) that can extend effective market protection even after one patent expires. Because Linzess has multiple patent families, the “last expiring” patent is often the practical date people look for rather than any single earlier patent.

DrugPatentWatch is useful here because it aggregates the different patent terms tied to the product and shows what’s expected to end and when. https://www.drugpatentwatch.com/patent/linzess-linaclotide

What if I meant exclusivity (not just patents)?

If you’re asking about the earliest time a competing product could launch, exclusivity can matter as much as patents. Patents protect specific inventions; exclusivity can come from regulatory approvals and can delay generic launches even after patent expiry. To answer precisely, you’d need to match your question to the exact patent number(s) or exclusivity type associated with Linzess in the relevant country.

DrugPatentWatch’s product page is the fastest way to identify which patents/exclusivities are listed for Linzess and their timelines. https://www.drugpatentwatch.com/patent/linzess-linaclotide
